EGG-TESTER.

SPECIFICATION forming part of Letters Patent No. 423,685, dated March 18, 1890.

I `Application filed July Z3, 1889. Serial No. 318,369. (No model.)

To all .whom it may concern:

Be it known that 1, FRANK HERRICK, of Rhinebeck, in the county of Dutchess and State of New York, have invented a new and useful Improvement in Egg-Testers, of which the following is a full, clear, and exact description.

My invention relates to an improvement in egg-testers, and has for its object to provide a device capable of expediting the workk of candling eggs and to vprovide a means whereby the eggs may be tested accurately p and conveniently in a lighted room.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters and iigures of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of the device. Fig. 2 is a perspective view withthe hood removed, and Fig. 3 is a central vertical section 16 of elastic material-such as leather, for

instance-inwhich material three triangularly-arranged openings 1 7 are produced, as best shown in Fig; 2. One lower opening a and the upper opening a are essentially oval, and the other lower openin g a2 is practically circular. At the rear ofthe strip 16 containing the openings a slide or damper 18 -is placed,.pivoted at one upper end, as shown. in Fig. 2, and provided with a segmental slot 19, through which a Vpin 20 is passed, as is also best shown in Fig. 2, which pin limits 'the upward movement of the damper or slide and guides it in its downward movement. The downward movement is limited by means of a stop 217 integral with the outer lower end of the damper, adapted to contact with one side edge of the apertured strip 16, and a handle 22, of any approved construction, is formed integral with or attached to the outer edge of the damper above the said lstop'. The damper is of such width that when it is carried downward to the closed position between the opposed faces of the door and the strip 16 it will cover only two of the openings 17- for instance, the openings d and CL2.

Vithin the box-like body 10 a bracket 23 is secured, on which bracket any form of lamp 24 is adapted to be located. I desire it, however, to be distinctly understood that I do not confine myself to any particular form of bracket, and that the said bracket may be dispensed with entirely and the lamp be placed upon the center of a spider 25, secured in the bottom of the box or at any point in its length.

In connection with a box constructed as described I employ a hood 26. This hood comprises a rigid top plate 27, to the front and side edges of which a piece of cloth 28 is attached, or any material which Will shade the openings covered by the strip 16. The top plate 27 is provided'at each side of the inner end with a bifurcated projection 29, which projections are adapted to 'pass over an'eye 30, secured to the edge of the door, and to the sides of the Vtop plate a hook 31 is pivqted, whereby the top plate of the hood is fastened to the door.V

As a further support for the hood, a bail 32 is pivoted to its sides, the upper portion of whichbail contacts with hooks33, secured to the door near its upper edge. Thus the hood may be very quickly applied and speedily detached when not wanted. The cloth of the hood is sufficiently long to extend down to a point at or near the bottom of the boxebody, where it may be secured iri any approved manner, preferably by a hook, as illustrated, and in the front of the cloth opposite the apertured strip 16 of the body an opening 34 is made suflicientto admit the face of the operator. The device is adapted to be hung upon the wall or other support at a convenient height for the operator to place his face at the opening 34.

In operation, when in a lighted room, the hood is attached to the box, and the operator,

IOO

placing his face in or near the opening 34,

graspsthe eggs in the usual manner-that is, three in each hand-and placing them over the openings a, a', and a2 is' enabled VWhile holding them to determine Whether they are fresh or not by the passage of the light through the shell.

If there is any doubt with reference to the freshness of a single egg, for instance, of the three, that egg is placed at one side, and the other two are dropped into a suitable receptacle," The damper 22 is then slid down, closing two of the openings, and the egg is placed at the single opening,lwhereby all the light is concentrated at that point.

By means ot this apparatus the operator is enabled to-take three eggs with each hand and pass them before the openings in the strip 16, thereby greatly expediting the operation of candling, which has heretofore been very tedious and has consumed considerable' time. When in a dark room, the hood need not be used.

I desire it to beunderstood that, if desirable, reflectors of any approved construction may be used in connection with the device.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In an egg-tester, the combination, With a box-like body having an opening in one side and means for supporting a lamp, of a strip of pliable material covering the body-opening, providedv With apertures triangularly.

grouped, and a damper held to slide beneath the said strip, capable of closing one or more of the apertures therein, substantially as shown and described.

2. In an egg-tester, the combination, With a box-like body provided with an essentially y FRANK HERRICK.
